Product Overview
A 24V, 200A contactor used to switch high-current power circuits on compatible JLG aerial lifts. The low-current control circuit energizes the coil, while the contactor terminals carry the much heavier motor or main-power load.
No drive/lift power, intermittent power or heavily burned contactor terminals can indicate contactor failure, but battery voltage, cable condition and control-coil voltage should be tested first.
Key Features & Performance
- Provides positive electrical actuation of the diesel shutoff mechanism.
- Useful for no-start, start-then-die or no-shutoff complaints after wiring/linkage checks.
- Reference-number matching helps avoid visually similar solenoids.
